Description

Technical Field

[0001] The present invention relates to the technical field of voltage inspection modules, and particularly to a semi-automatic detection device for a hydrogen fuel cell CVM. Background Art

[0002] CVM, namely the voltage inspection module, is a bridge between the fuel cell and the external world. The CVM can collect and process voltage information and AC impedance information during the operation of the fuel cell in real time, interact with an external host, and send it to the fuel cell system controller. By checking the single-cell voltage signal, the working state of the fuel cell can be judged, and corresponding control operations can be performed to solve key problems such as the safety, usability, ease of use, and service life of the fuel cell, and it has been widely used in the commercial or industrial hydrogen fuel cell field.

[0003] For voltage inspection, there are different shapes. Some CVMs on the market are made rather crudely and are very inconvenient to use. For example, some signal wires are connected wrongly, and some signal wires fall off. In addition, some CVMs have low sensitivity, and problems can only be found after being assembled into the hydrogen fuel cell system, and some even cause the fuel cell stack to burn out, etc. However, the current detection method for the voltage inspection module is still to check each plug with a multimeter. There are many pins inside each plug, so the inspection efficiency is low and there is also a risk of missed inspection. Therefore, a special detection device is needed for detection. Summary of the Invention

[0004] The purpose of the present invention is to solve the drawbacks existing in the prior art, and to propose a semi-automatic detection device for a hydrogen fuel cell CVM.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] A semi-automatic detection device for a hydrogen fuel cell CVM includes a mounting frame.

[0007] Preferably, a junction box and a control panel are fixed on the outer wall of the top of the mounting frame. Communication lines are respectively inserted into the outer walls of one side of the voltage inspection module, the junction box and the control panel. The voltage inspection module, the electric slide rail and the first electric push rod are respectively electrically connected to the control panel.

[0008] Further, the automatic clamping mechanism includes a second electric push rod, a pressing plate, an elastic telescopic rod, a buffer plate, an L-shaped clamping block, a top plate and a fixing rod. A rectangular through hole is formed in the outer wall of one side of the connecting frame. The fixing rod is slidably connected to the inner wall of the rectangular through hole. The top plate is fixed on the outer wall of one side of the fixing rod. The L-shaped clamping block is fixed on the outer wall of the top of the mounting frame. The second electric push rod is fixed on the outer wall of the top of the mounting frame. The pressing plate is fixed on the output shaft of the second electric push rod. The elastic telescopic rod is fixed on the outer wall of one side of the pressing plate. The buffer plate is fixed on the outer wall of one side of the elastic telescopic rod. The second electric push rod is electrically connected to the control panel. The fixing rod is fixed on the outer wall of one side of the connecting frame.

[0009] More preferably, a snap ring is fixed on the outer wall of the conductive plug, and a card slot is formed in the inner wall of the jack.

[0010] As a preferred embodiment of the present invention: a guide plate is fixed on the outer wall of the top of the movable mounting block. The connecting column is slidably connected to the outer wall of one side of the guide plate. A limiting frame is fixed on the outer wall of the bottom of the connecting column. The top of the detection plug is fixed on the outer wall of the bottom of the limiting frame.

[0011] As a further preferred embodiment of the present invention: a scale is adhered to the outer wall of one side of the mounting frame. A pointer is fixed on the outer wall of the bottom of the L-shaped sliding plate. A handle is fixed on the outer wall of one side of the L-shaped sliding plate.

[0012] As a further scheme of the present invention: a plurality of rectangular through grooves are formed in the outer wall of the top of the mounting frame. Guide sleeves are fixed in the inner walls of the rectangular through grooves. Plug rods are fixed in the inner walls of the guide sleeves.

[0013] On the basis of the foregoing scheme: a protection frame is fixed on the outer wall of the bottom of the mounting frame. The battery box is inserted into the inner wall of the protection frame. A line protection sleeve is inserted into the outer wall of one side of the protection frame. The line protection sleeve penetrates through the outer wall of the top of the mounting frame. The outer wall of one side of the line protection sleeve is inserted into the outer wall of one side of the movable plate. A ventilation window is fixed on the outer wall of one side of the battery box.

[0014] Preferably on the basis of the foregoing scheme: a second infrared pair of light sensors and a first infrared pair of light sensors are respectively fixed on the outer walls of one side of the connecting column and the movable plate. The first infrared pair of light sensors and the second infrared pair of light sensors are respectively electrically connected to the control panel.

[0015] The beneficial effects of the present invention are:

[0016] 1. Control the electric slide rail through the control panel to drive the moving plate to move to the position where the conductive plug and the jack are aligned with each other. Subsequently, the control panel will control the first electric push rod to push the push plate downward, so that the conductive plug is inserted into the jack. At this time, the battery installed inside the battery box will send current into the corresponding plug-in on the voltage inspection module through the line protection sleeve, the conductive plug and the detection plug, so that the voltage inspection module can detect the voltage of the input current through this plug-in. Subsequently, the voltage inspection module will send the detection data into the control panel through the communication line and the junction box. When the measured voltage is the normal voltage of the battery installed inside the battery box, it means that this plug-in can work normally. At this time, the control panel controls the first electric push rod to reset and controls the electric slide rail to drive the moving plate to continue to move forward, and detects the remaining plug-ins through multiple moving mounting blocks fixed on the subsequent mounting frame, effectively improving the detection efficiency.

[0017] 2. The voltage inspection module is effectively clamped by the L-shaped clamp block, the buffer plate and the top plate. After the plug-in installed on the voltage inspection module is detected, the staff can control the second electric push rod to reset through the control panel, so as to release the fixation of the voltage inspection module. Subsequently, the staff can replace the voltage inspection module. The staff can conveniently adjust the L-shaped clamp block, the fixed rod and the pushing distance of the second electric push rod according to the voltage inspection module of different sizes, so that the automatic clamping mechanism can clamp and fix the voltage inspection module of different models.

[0018] 3. The staff can replace the detection plug according to the different models of the voltage inspection module, so that the detection plug can be inserted into the plug-ins on the voltage inspection modules of different models. At the same time, the limit frame can limit the movement of the connecting column; the staff can easily pull the moving mounting block to slide left and right on the inner wall of the mounting frame through the handle, and accurately adjust the position of the moving mounting block through the pointer and the scale, so that the detection plug at the bottom of the moving mounting block can be accurately inserted into the plug-in on the top of the voltage inspection module.

[0019] 4. When the push plate drives the moving plate to move upward, the connecting column will pull out the detection plug installed at the bottom from the plug-in on the top of the voltage inspection module under the pulling of the conductive plug and the elastic force of the spring, avoiding the detection plug being always inserted on the voltage inspection module, which makes it inconvenient for the subsequent staff to remove the voltage inspection module from the mounting rack. After the voltage inspection module is detected, the control panel can be used to control the automatic clamping mechanism to release the clamping and fixation of the voltage inspection module. Subsequently, the voltage inspection module can be removed from the mounting rack and a new voltage inspection module can be placed on the mounting rack for continued detection.

[0020] 5. When the staff controls the electric slide rail to drive the moving plate to move through the control panel, when the moving plate moves to the top of the corresponding connecting column, the first infrared pair sensor and the second infrared pair sensor will complete the pair shooting. At this time, the control panel will control the electric slide rail to stop running, and at the same time control the first electric push rod to push the push plate downward, so that the conductive plug and the jack can be accurately positioned, and the detection device can quickly and accurately detect the voltage inspection module.

[0034] Embodiment 1:

[0035] A semi-automatic detection device for a hydrogen fuel cell CVM, as Figure 1-8As shown in the figure, it includes a mounting bracket 1. An automatic clamping mechanism and a voltage inspection module 16 are provided on the outer wall of the top of the mounting bracket 1. A support plate 4 and a connecting bracket 6 are fixed to the outer wall of the top of the mounting bracket 1 by screws. A first electric push rod 7 is fixed to the outer wall of one side of the connecting bracket 6 by screws. First, the staff places the voltage inspection module 16 to be detected on the top of the mounting bracket 1, and then controls the automatic clamping mechanism to clamp and fix the voltage inspection module 16 through the control panel 10. The output shaft of the first electric push rod 7 is fixed to a push plate 5 by screws. An electric slide rail 8 is provided on the outer wall of the bottom of the push plate 5. A moving plate 25 is slidably connected to the inner wall of the electric slide rail 8. A conductive plug 40 is inserted into the outer wall of the bottom of the moving plate 25. A plug rod 2 is fixed to the outer wall of the top of the mounting bracket 1 by screws. An installation frame 3 is fixed to the outer wall of the top of the plug rod 2 by screws. A moving installation block 36 is slidably connected to the inner wall of the installation frame 3. L-shaped sliding plates 35 are respectively welded to the outer walls of both sides of the moving installation block 36. Threaded through holes are respectively formed in the L-shaped sliding plates 35 and the outer wall of the top of the installation frame 3.

[0036] The staff places the same number of moving installation blocks 36 on the installation frame 3 according to the number of plugs on the top of the voltage inspection module 16. Then, the moving installation block 36 is slid left and right through the installation frame 3 so that the detection plug 33 installed at the bottom of the connecting column 27 can be aligned with the corresponding plug on the voltage inspection module 16. Then, screws can be used to fix the L-shaped sliding plate 35 to the installation frame 3, thus completing the fixation of the position of the moving installation block 36. After all the moving installation blocks 36 slidably connected inside the installation frame 3 are fixed by screws according to the above steps, the control panel 10 can be used to control the electric slide rail 8 to drive the moving plate 25 to move to the position where the conductive plug 40 is aligned with the jack 38. Then, the control panel 10 will control the first electric push rod 7 to push the push plate 5 downward, so that the conductive plug 40 is inserted into the jack 38. At this time, the battery installed inside the battery box 11 will send current into the corresponding plug on the voltage inspection module 16 through the line protection sleeve 19, the conductive plug 40 and the detection plug 33, so that the voltage inspection module 16 can detect the voltage of the input current through this plug. Then, the voltage inspection module 16 sends the detection data into the control panel 10 through the communication line 21 and the junction box 9. When the measured voltage is the normal voltage of the battery installed inside the battery box 11, it means that this plug can work normally. At this time, the control panel 10 controls the first electric push rod 7 to reset, and controls the electric slide rail 8 to drive the moving plate 25 to continue to move forward, and the remaining plugs are detected through the multiple moving installation blocks 36 fixed on the subsequent installation frame 3;

[0037] A connecting column 27 is slidably connected to the inner wall of the movable mounting block 36. A detection plug 33 is provided on the outer wall of the bottom of the connecting column 27. Pressure blocks 29 are respectively welded to the outer walls on both sides of the connecting column 27. A spring 30 is fixed to the outer wall of the bottom of the pressure block 29 by screws. When the push plate 5 drives the movable plate 25 to move upward, the connecting column 27 will, under the pulling of the conductive plug 40 and the elastic force of the spring 30, pull out the detection plug 33 installed at the bottom from the inside of the plug on the top of the voltage inspection module 16, preventing the detection plug 33 from being always inserted into the voltage inspection module 16, which may cause inconvenience for subsequent staff to remove the voltage inspection module 16 from the mounting rack 1. After the voltage inspection module 16 is detected, the automatic clamping mechanism can be controlled through the control panel 10 to release the clamping and fixation of the voltage inspection module 16. Subsequently, the voltage inspection module 16 can be removed from the mounting rack 1 and a new voltage inspection module 16 can be placed on the mounting rack 1 for continued detection, effectively improving the detection efficiency. The spring 30 is fixed to the outer wall of the top of the movable mounting block 36 by screws. A jack 38 is provided on the outer wall of the top of the connecting column 27. A junction box 9 and a control panel 10 are fixed to the outer wall of the top of the mounting rack 1 by screws. Communication lines 21 are respectively inserted into the outer walls of the voltage inspection module 16, the junction box 9, and the control panel 10. The voltage inspection module 16, the electric slide rail 8, and the first electric push rod 7 are respectively electrically connected to the control panel 10.

[0038] In order to effectively clamp and fix the voltage inspection module 16; as Figure 1 , Figure 2 , Figure 4 shown, the automatic clamping mechanism includes a second electric push rod 13, a pressing plate 14, an elastic telescopic rod 23, a buffer plate 22, an L-shaped clamping block 15, a top plate 17, and a fixing rod 18. A rectangular through hole is provided on the outer wall of one side of the connecting frame 6. The fixing rod 18 is slidably connected to the inner wall of the rectangular through hole. The top plate 17 is fixed to the outer wall of one side of the fixing rod 18 by screws. The L-shaped clamping block 15 is fixed to the outer wall of the top of the mounting rack 1 by screws. The second electric push rod 13 is fixed to the outer wall of the top of the mounting rack 1 by screws. The pressing plate 14 is fixed to the output shaft of the second electric push rod 13 by screws. The elastic telescopic rod 23 is fixed to the outer wall of one side of the pressing plate 14 by screws. The buffer plate 22 is fixed to the outer wall of one side of the elastic telescopic rod 23 by screws. The second electric push rod 13 is electrically connected to the control panel 10. The fixing rod 18 is fixed to the outer wall of one side of the connecting frame 6 by screws.

[0039] The staff member pushes the fixing rod 18 forward by an appropriate distance, then fixes the fixing rod 18 on the connecting frame 6 with screws. Subsequently, the voltage inspection module 16 is placed against one side of the top plate 17 on the mounting frame 1, and the outer walls on both sides of the voltage inspection module 16 are clamped by the L-shaped clamping blocks 15. Then, the L-shaped clamping blocks 15 are fixed on the mounting frame 1 with screws. At this time, the control panel 10 can be used to control the second electric push rod 13 to push the pressing plate 14 forward. The pressing plate 14 will push the buffer plate 22 through the elastic telescopic rod 23 to squeeze one side of the voltage inspection module 16. When the second electric push rod 13 pushes the pressing plate 14 forward by a set distance, the control panel 10 will control the second electric push rod 13 to stop pushing. At this time, the voltage inspection module 16 is effectively clamped by the L-shaped clamping blocks 15, the buffer plate 22 and the top plate 17, thus completing the fixation of the position of the voltage inspection module 16. When the plug installed on the voltage inspection module 16 is detected, the staff member can control the second electric push rod 13 to reset through the control panel 10, thereby releasing the fixation of the voltage inspection module 16. Subsequently, the staff member can replace the voltage inspection module 16. The staff member can conveniently adjust the pushing distance of the L-shaped clamping blocks 15, the fixing rod 18 and the second electric push rod 13 according to the voltage inspection module 16 of different sizes, so that the automatic clamping mechanism can clamp and fix the voltage inspection module 16 of different models.

[0040] In order to enable the conductive plug 40 to be inserted more firmly into the jack 38; as Figure 5 , Figure 7 shown, a snap ring 39 is fixed on the outer wall of the conductive plug 40, and a card slot 37 is formed on the inner wall of the jack 38; when the conductive plug 40 is inserted into the jack 38, the snap ring 39 on the outer wall of the conductive plug 40 will snap into the card slot 37 on the inner wall of the jack 38, thereby making the connection between the conductive plug 40 and the jack 38 more firm. When the conductive plug 40 rises with the moving plate 25, the conductive plug 40 can pull the connecting column 27 upward more stably through the connection between the snap ring 39 and the jack 38. When the connecting column 27 rises to an appropriate height, the push plate 5 will pull the moving plate 25 to continue rising, thereby pulling the snap ring 39 out of the jack 38.

[0041] In order to improve the stability of the connecting column 27 when moving up and down; as Figure 5 , Figure 6 , Figure 7As shown, a guide plate 34 is fixed to the outer wall of the top of the movable mounting block 36 by screws. A connecting column 27 is slidably connected to the outer wall of one side of the guide plate 34. A limiting frame 32 is fixed to the outer wall of the bottom of the connecting column 27. The outer wall of the top of the detection plug 33 is fixed to the outer wall of the bottom of the limiting frame 32 by screws. The staff can replace the detection plug 33 according to different models of the voltage inspection module 16, so that the detection plug 33 can be inserted into the plug-ins on different models of the voltage inspection module 16. At the same time, the limiting frame 32 can limit the movement of the connecting column 27 to prevent the connecting column 27 from being easily pulled out of the movable mounting block 36, and the guide plate 34 can guide the up and down movement of the connecting column 27.

[0042] To facilitate the adjustment of the position of the movable mounting block 36; as Figure 5 、 Figure 6 shown, a scale is adhered to the outer wall of one side of the mounting frame 3. A pointer 31 is fixed to the outer wall of the bottom of the L-shaped sliding plate 35. A handle is fixed to the outer wall of one side of the L-shaped sliding plate 35 by screws. The staff can easily pull the movable mounting block 36 to slide left and right on the inner wall of the mounting frame 3 through the handle, and accurately adjust the position of the movable mounting block 36 through the pointer 31 and the scale, so that the detection plug 33 at the bottom of the movable mounting block 36 can be accurately inserted into the plug on the top of the voltage inspection module 16.

[0043] To facilitate the adjustment of the height of the mounting frame 3; as Figure 1-4 shown, a plurality of rectangular through grooves are formed in the outer wall of the top of the mounting frame 1. A guide sleeve 24 is fixed to the inner wall of the rectangular through groove. A plug rod 2 is fixed to the inner wall of the guide sleeve 24 by screws. The staff can slide the plug rod 2 up and down through the guide sleeve 24 to adjust the height of the mounting frame 3. After the position of the plug rod 2 is adjusted, the plug rod 2 can be fixed to the guide sleeve 24 by screws, so that the plug rod 2 can effectively support the mounting frame 3.

[0044] To enable the battery inside the battery box 11 to be stably connected to the conductive plug 40; as Figure 1 、 Figure 2 、 Figure 3 、 Figure 4As shown in the figure, a protection frame 12 is fixed to the outer wall of the bottom of the mounting bracket 1 by screws. The battery box 11 is inserted into the inner wall of the protection frame 12. A line protection sleeve 19 is inserted into the outer wall of one side of the protection frame 12. The line protection sleeve 19 penetrates through the outer wall of the top of the mounting bracket 1. The outer wall of one side of the line protection sleeve 19 is inserted into the outer wall of one side of the moving plate 25. A ventilation window 20 is fixed to the outer wall of one side of the battery box 11 by screws. The staff places the power supply battery into the battery box 11, then inserts the battery box 11 into the protection frame 12, and connects the battery inside the battery box 11 to the moving plate 25 through a power transmission line. At this time, the line protection sleeve 19 can effectively protect the power transmission line, avoiding damaging the power transmission line when the moving plate 25 moves left and right. At the same time, the ventilation window 20 can dissipate heat from the battery inside the battery box 11.

[0045] When this embodiment is in use, the staff first places the voltage inspection module 16 to be detected on the top of the mounting bracket 1, and then controls the automatic clamping mechanism to clamp and fix the voltage inspection module 16 through the control panel 10. The staff places the same number of moving mounting blocks 36 on the mounting frame 3 according to the number of plugs on the top of the voltage inspection module 16. Then, the moving mounting blocks 36 are slid left and right on the mounting frame 3 so that the detection plugs 33 installed at the bottom of the connecting column 27 can be aligned with the plugs at the corresponding positions on the voltage inspection module 16. Then, the L-shaped sliding plate 35 can be fixed to the mounting frame 3 with screws. After all the moving mounting blocks 36 slidably connected inside the mounting frame 3 are fixed with screws according to the above steps, the control panel 10 can control the electric slide rail 8 to drive the moving plate 25 to move to the position where the conductive plug 40 and the jack 38 are aligned with each other. Then, the control panel 10 will control the first electric push rod 7 to push the push plate 5 downward, so that the conductive plug 40 is inserted into the jack 38. At this time, the battery installed inside the battery box 11 will send current into the corresponding plug on the voltage inspection module 16 through the line protection sleeve 19, the conductive plug 40 and the detection plug 33. Then, the voltage inspection module 16 will send the detection data into the control panel 10 through the communication line 21 and the junction box 9. When the measured voltage is the normal voltage of the battery installed inside the battery box 11, it means that the plug can work normally. At this time, the control panel 10 controls the first electric push rod 7 to reset, and controls the electric slide rail 8 to drive the moving plate 25 to continue to move forward, and the remaining plugs are detected through the multiple moving mounting blocks 36 fixed on the subsequent mounting frame 3.

[0046] When the push plate 5 drives the moving plate 25 to move upward, the connecting column 27 will pull out the detection plug 33 installed at the bottom from inside the plug on the top of the voltage inspection module 16 under the pulling of the conductive plug 40 and the elastic force of the spring 30. After the voltage inspection module 16 is detected, the automatic clamping mechanism can be controlled through the control panel 10 to release the clamping and fixing of the voltage inspection module 16. Subsequently, the voltage inspection module 16 can be removed from the mounting rack 1 and a new voltage inspection module 16 can be placed on the mounting rack 1 for continuous detection. The staff pushes the fixing rod 18 forward by an appropriate distance, and then fixes the fixing rod 18 to the connecting frame 6 with screws. Subsequently, the voltage inspection module 16 is placed on the mounting rack 1 against one side of the top plate 17, and the outer walls on both sides of the voltage inspection module 16 are clamped by the L-shaped clamping blocks 15. Then, the L-shaped clamping blocks 15 are fixed to the mounting rack 1 with screws. At this time, the second electric push rod 13 can be controlled through the control panel 10 to push the pressing plate 14 forward. The pressing plate 14 will push the buffer plate 22 through the elastic telescopic rod 23 to squeeze one side of the voltage inspection module 16. When the second electric push rod 13 pushes the pressing plate 14 forward by a set distance, the control panel 10 will control the second electric push rod 13 to stop pushing. At this time, the voltage inspection module 16 is effectively clamped by the L-shaped clamping blocks 15, the buffer plate 22 and the top plate 17.

[0047] After the plug installed on the voltage inspection module 16 is detected, the staff can control the second electric push rod 13 to reset through the control panel 10, so as to release the fixation of the voltage inspection module 16. Subsequently, the staff can replace the voltage inspection module 16. The staff can replace the detection plug 33 according to the different models of the voltage inspection module 16, so that the detection plug 33 can be inserted into the plugs on different models of voltage inspection modules 16.
